I am unable to access my internal servers via the external IP address from devices connected via ethernet to my router. 

Devices that are connected to wireless or vpn are able to access the interal servers correctly via port forwarding. 

Using either DDNS or WAN IP address I cannot access interal servers from a device on the local wired network, however i can access those servers via the interal IP address

it seems that the nat loopback issue was fixed on other devices in newere firmware but no this one. Any suggestions?
